Letters Patent No. 75,166, dated llfarclt 1868,

IMPROVED HOP-'PRESSi art-strata were it in the: Elders time nutmnti'ngpzittttmam.-

TO ALL WHOM IT MAYUONCERI a Beit knownthat I, Jhiuns HU'rcnINsoN, ofFond du Lac, in the county of Fond du Lac, and 'State ot' Wisconsin,"have invented certain new and useful Improvements inHop-Presses; and I do hereby declare that the following is-afull,'-clear, and exact description 'th'ereoi', reference being bad tothe accompanying drawings making part of'this specification, and to theletters of reference marked thereon, likelette'rs indicating like partswherever they occur. x

To enable others sk-illed'in tlie art to eonstructand use my invention,I w'ilI proceed to describe it. My invention relates to presses for hopsand similar purposes, and consists of new, useful, and certainimproyements in the hop-press for which Letters Patent, dated July16,1867, No. 66,793, were granted to Newell Carpenter and myself, bywhich I am enabled-to make it more eflioient for the purposes for whichit is designed, In the drawings-- Figu're'l is a view ofa longitudinalvertical section, and V Figure 2 is an end view, with the ban Llle ofthe leverleft oil, and a portion of the movable block broken away. Iconstruct the bed A, the upright, B, madaby slotting a single piece oftimber, or ofitwo pieces, with a block' interpbsed between their lowerends, and provided with the plates 0, having ratchetvteeth on theirinterim: surfaces and on their inner edges, as shown in figs. 1 and 2,and fully described in said Letters Patent, No. 66,793. The beam D,which is presscd-(lown by the mechanical arrangement hereinafterdescribed, is'provided with the pawl s a, which are held in placeagainst the ratchet-teeth on the inner edges of thelplates C by thesprings'b, as shown in fig. 1, and the movable block E-is arranged toslide vertically in the upright,-B, and is provided with the'dogs c,which are held in plaoe by the springs d, as shown in fig. 2,and-described in said Let-- tersPatent. Near theend of the cross-bar orbeam D, on its upper side, and so as to be within the slot of theupright, B, I mount a roller,F, flanged or not, as may be, desired,between two strong bearings, e, which are firmly attached to the beam D,as shown in figs. 1 and 2, and tothe lower side of the block E, atf, I-'p ivot the head, H, of the' lever G. The lower side of the. head, H,of the lever G I shape or curve, so as to makeit eccentric, about thepointf, so that the-distance from the pointfto the lower side of the-headot'the leveriwill constantly increase on either side of a linerunning through the centre of the upright, B, when-the lcve'rvs'tands atright angles to this upright, as shown in fig. 1. I provide each end ofmy press with thismechanical arrangement, and, in operating it, placethe hops or other substance to be pressed between the-bed .AQ-and beatnl), th en squeeze together the dogs 0, if necessary, and drop the blocksF till the heads H of the lovers come in. contact with therollers-F,then work the levers by moving their. handles up'and down As the headHis eccentric, as; it moves backwardand forward over the roller-F, itwill continue to press from one endof its curve to the other.Asthe-bea'm D'is'p'ressed'down, the pawls more with it, and hold it inplace. [At the same time the block E follows down, and is held in placeby the dogs 0. Both endsof the press are worked at the same time. .WhenI p the hops or'other substancenre sufliciently pressed, theyarcbaled..' The beam D is again adjusted by s'queezing the dogs 0 andelevating or raising the blocks Eyand the process repeated zisbefore. Ii i 'In the Letters Patent mentioned, the pressure was not constant, andceased whenever the handle of the lever was elevated or lowered above orbelow a certain point. By the use of the eccentric-head H, as hereindescribed, the pressure becomes greater as the handle of the lever iselevated or lowered" rendered easier by the use of the friction-rollerF,'a nd in.this wayI a'menabled to construct and-furnish a press havinggreat advantages over the one for which the Letters Patent werepreviously granted to me, and as being a. greatimprovemcnt on the same.

Having thus described my invention, what I claim is The improvedmechanical arrangement for pressing hops and similar substances,consisting of the hinged. lever-G, with its eccentric-head H, block E,provided with the dogs a, in combination with the ratchet-plates C andbeam D, provided with the'roller F and pawls a, when constructed andarranged to operate as described.
